This topic describes how to stop the sender channel on
a WebSphere® MQ link while
leaving the link itself running.
Before you begin
Note: If you stop the sender channel on a WebSphere MQ link, communication with the
target WebSphere MQ network
on that channel will cease for both point-to-point messaging and publishing
and subscribing. Messages will be held at their transmission locations.
You
may wish to warn the administrator of the WebSphere MQ network that you are about
to stop a channel.
About this task
To stop the sender channel on a WebSphere MQ link use the administrative
console to complete the following steps:
Procedure
- In the navigation pane, click bus_name link_name.
- Click the sender channel you want to stop.
- Select the check box next to the channel you want to stop.
- In the Stop mode list, select Quiesce
or Force.
- In the Target state list, select
Inactive or Stopped.
- Click Stop.
Results
Only the sender channel is affected by this procedure. The
resultant state of the sender channel depends on the options you chose:
